Abstract :
The experiments of different dose rate radiation induced Charge Coupled Devices (CCD) functional failure are presented. The CCDs are divided into three groups with no shielding, shielding the output amplifiers, and shielding the photo sensing and the shift register areas with Pb during 60Co γ tests. The radiation tolerance depend on the dose rates whether the linear CCDs are shielded or not. The total doses to functional failure of the CCDs at different dose rate radiation are compared. The criterion of functional failure induced by ionization radiation is ascertained. The mechanism of CCD functional failure is analyzed.
